#! at the end of the URL redirects to the main page

I'm developing an application on a meteor using the iron-router. Search engine Yandex indexes pages incorrectly because of its error and adds at the end of url #!, for example: https://site.com/posts/post-name#!. The iron-router does not handle this URL correctly and the page is redirected to the URL of the main page, for example: https://site.com
Is it possible to have the iron-router handle the correct #! at the end of URL?
